Description

Technical Field

[0001] The present invention relates to the technical field of atomizer cores, and in particular to an atomizer core, a calculation method for liquid guide holes, and a storage medium. Background Art

[0002] The liquid storage tank of the atomizer core is provided with a liquid guide hole, which is used to guide the atomized liquid in the liquid storage tank to the atomizer component. The atomized object atomizes the atomized liquid by heating or ultrasonic waves.

[0003] Among them, the proportion of the liquid guide hole on the atomized liquid adsorption surface (or the size of the liquid guide hole) has an important impact on the use effect of the atomizer core. The liquid guide hole connects the atomized liquid storage bin and the liquid guide medium of the liquid absorption and storage. If the liquid guide hole is too large, the atomized liquid will leak from the gas channel under the action of capillary force in the static state, causing unnecessary waste; if the liquid guide hole is too small, the liquid guide medium cannot guarantee the timely supply of the atomized liquid in the working state, affecting the atomization effect and user experience.

[0004] At present, the opening of the liquid guide holes is obtained through multiple experiments and is set based on the experience of designers. There is no clear range for the specific proportion, the specifications of the atomizer cores are varied, and the atomization effect produced by the manufactured liquid guide holes is not ideal. Summary of the invention

[0005] The main technical problem solved by the present invention is that the proportion of the liquid guide holes in the existing atomizer core is set based on experience, and the atomization effect of the atomizer core is not good and the effect is not ideal.

[0007] The liquid storage tank is used to store the atomized liquid. A liquid guide hole is provided on the tank wall of the liquid storage tank. The atomized liquid in the liquid storage tank penetrates into the liquid guide medium through the liquid guide hole. The liquid guide medium is used to adsorb the atomized liquid. The atomizing assembly is used to atomize the atomized liquid adsorbed by the liquid guide medium. The proportion of the liquid guide hole relative to the adsorption surface of the liquid guide medium is greater than or equal to the first proportion and less than or equal to the second proportion.

[0009] The second proportion is calculated based on the liquid absorption mass of the liquid-conducting medium in a static state, and at least one of the area of ​​the adsorption surface of the liquid-conducting medium, the liquid conduction volume of the liquid-conducting hole, and a preset standard standing time.

[0010] According to the second aspect, an embodiment provides a method for calculating a liquid guide hole, which is applied to an atomizer core. The atomizer core includes a liquid storage tank, a liquid guide medium, and an atomizer component. The liquid storage tank is used to store atomized liquid.

The liquid guide medium is used to absorb the atomized liquid. The atomizer component is used to atomize the atomized liquid absorbed by the liquid guide medium.

[0011] The calculation methods include:

[0013] A second ratio is obtained according to the liquid absorption mass of the liquid-conducting medium in a static state, and at least one of the area of ​​the adsorption surface of the liquid-conducting medium, the liquid conduction volume of the liquid-conducting hole, and a preset standard static time;

[0014] The proportion of the liquid conducting hole relative to the adsorption surface of the liquid conducting medium is determined according to the first proportion and the second proportion; wherein the proportion is greater than or equal to the first proportion and less than or equal to the second proportion, and the first proportion is less than or equal to the second proportion.

[0015] In a third aspect, an embodiment provides a computer-readable storage medium, on which a program is stored, and the program can be executed by a processor to implement the computing method described in the second aspect.

Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0022] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0023] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0024] The atomizer core, which may also be called an atomizer, an atomizer structure or an atomizer device, is generally used in multiple occasions such as atomization therapy, environmental atomization, and electronic cigarettes.

[0025] The atomization component of the atomization core can be airflow atomization, heating atomization or ultrasonic atomization. The atomization components commonly used in electronic cigarettes are generally heating atomization, the atomizer is generally ultrasonic atomization, and the atomization therapy device can be airflow atomization, heating atomization or ultrasonic atomization.

[0026] In the embodiment of the present invention, the atomizer core using heating atomization is mainly used. By controlling the size of the liquid guide hole, it is ensured that there is no leakage in the static state and the liquid is supplied in time in the working state, so as to provide a good atomization effect and use effect. However, the application of atomizer cores with other atomization forms is not excluded.

[0027] Embodiment 1:

[0028] Please refer to Figure 1This embodiment provides an atomizing core, including: a liquid storage tank 1, a liquid guiding medium 2, and an atomizing assembly 3. The liquid storage tank 1 is used to store atomized liquid, and a liquid guiding hole 12 is provided on a tank wall 11 of the liquid storage tank 1. The atomized liquid in the liquid storage tank 1 penetrates into the liquid guiding medium 2 through the liquid guiding hole 12; the liquid guiding medium 2 is used to absorb the atomized liquid; and the atomizing assembly 3 is used to atomize the atomized liquid absorbed by the liquid guiding medium 2.

[0029] In practical applications, such as Figure 1 As shown, the atomizing assembly 3, the liquid-conducting medium 2 and the liquid storage tank 1 are arranged from the inside to the outside, the liquid-conducting medium 2 can be a ring-shaped columnar structure, and the liquid-conducting hole 12 is arranged facing the outer cylindrical surface of the liquid-conducting medium 2. At this time, the adsorption surface of the liquid-conducting medium 2 corresponds to the outer cylindrical surface, and the atomizing assembly 3 is arranged inside the liquid-conducting medium 2.

[0030] For example, when the atomizing component 3 is a heating type atomizing component 3, the liquid-conducting medium 2 can be arranged around the periphery of the atomizing component 3, the liquid-conducting medium 2 is adjacent to or in contact with the atomizing component 3, and the inner cavity of the atomizing component 3 forms a gas channel. The atomizing component 3 atomizes part of the atomized liquid (such as the contacted part) of the liquid-conducting medium 2 by heating, and the atomized atomized liquid forms a gas that flows into the gas channel. When the user uses the atomizer, the airflow generated by breathing carries away the atomized liquid in the gas channel. Among them, the liquid-conducting medium 2 is generally a porous material that can absorb the atomized liquid, such as a fiber material, and a suitable material is selected according to the atomization temperature.

[0031] Of course, the atomization assembly 3 can also be an ultrasonic atomization type or an airflow atomization type. The liquid guide hole 12 of the liquid storage tank 1 penetrates to the atomized position through the liquid guide medium 2. The structural layout of the atomization core can be changed according to the specific atomization method.

[0032] The atomizer core provided in the present application has a ratio of the liquid-conducting hole 12 relative to the adsorption surface of the liquid-conducting medium 2 that is greater than or equal to the first ratio and less than or equal to the second ratio; the first ratio is less than or equal to the second ratio. The first ratio is calculated from at least one of the mass of liquid adsorbed by the liquid-conducting medium 2 in the working state, the dynamic viscosity of the atomized liquid, and the cross-sectional thickness of the liquid-conducting medium 2, as well as the permeability of the liquid-conducting medium 2, the internal and external pressure difference of the liquid-conducting medium 2, the density of the atomized liquid, the area of ​​the adsorption surface of the liquid-conducting medium 2, and the working duration of the atomizer core each time; the second ratio is calculated from at least one of the mass of liquid adsorbed by the liquid-conducting medium 2 in the static state, the area of ​​the adsorption surface of the liquid-conducting medium 2, the amount of liquid conducted by the liquid-conducting hole 12, and the preset standard standing time.

[0033] For example, the first proportion is calculated by the liquid absorption mass of the liquid-conducting medium 2 in the working state, the dynamic viscosity of the atomized liquid, the cross-sectional thickness of the liquid-conducting medium 2, the permeability of the liquid-conducting medium 2, the internal and external pressure difference of the liquid-conducting medium 2, the density of the atomized liquid, the area of ​​the adsorption surface of the liquid-conducting medium 2, and the working duration of the atomizer core each time; the second proportion is calculated by the liquid absorption mass of the liquid-conducting medium 2 in the static state, the area of ​​the adsorption surface of the liquid-conducting medium 2, the liquid conduction amount of the liquid-conducting hole 12, and the preset standard standing time.

[0034] In practical applications, the first ratio allows the liquid-conducting medium 2 to absorb at least a preset single atomization amount of atomized liquid during each working period of the atomizer core, and the second ratio allows the liquid-conducting medium 2 to absorb just enough atomized liquid during a preset standard resting time.

[0035] Specifically, the adsorption surface of the liquid-conducting medium 2 may be the surface of the liquid-conducting medium 2 that first adsorbs the atomized liquid. Figure 1 As shown, assuming that the upper and lower ends of the atomizer core are sealed, the liquid-conducting medium 2 is in a cylindrical shape, the atomizer assembly 3 can only atomize the atomized liquid on the inner side of the liquid-conducting medium 2, and the atomized liquid in the liquid storage tank 1 can only penetrate inward from the outer side of the liquid-conducting medium 2. At this time, the area of ​​the adsorption surface of the liquid-conducting medium 2 refers to the area of ​​the outer cylindrical surface of the liquid-conducting medium 2.

[0036] The structure of the atomizer core is varied, but the liquid-conducting medium 2 itself has a specific shape, that is, the outer surface of the liquid-conducting medium 2 can be confirmed, and the adsorption surface of the liquid-conducting medium 2 must be smaller than or equal to its outer surface. Figure 1 The atomizer core structure is used as an example for explanation, but the actual structure of the atomizer core that can be used in this application is not limited.

[0037] like Figure 1 As shown, there may be only one liquid conducting hole 12 disposed on the tank wall 11 of the liquid storage tank 1; or, there may be multiple liquid conducting holes 12 disposed on the tank wall 11 of the liquid storage tank 1, and the total area of ​​the multiple liquid conducting holes 12 may account for a ratio greater than or equal to the first ratio and less than or equal to the second ratio relative to the adsorption surface of the liquid conducting medium 2. The multiple liquid conducting holes 12 may be symmetrically disposed on the tank wall 11.

[0038] For example, the first proportion may range from 50% to 60%, and / or the second proportion may range from 70% to 80%.

[0039] In the present application, the liquid guide hole 12 on the bin wall 11 is reasonably arranged to ensure that the liquid guide hole 12 does not occupy too small a proportion, and the liquid guide medium 2 can quickly absorb the atomized liquid and replenish it in time when in the working state. Ensure that the liquid guide hole 12 does not occupy too large a proportion, and in the static state, ensure that the liquid guide medium 2 does not leak.

[0040] Embodiment 2:

[0041] In the present application, the proportion of the liquid guide holes 12 of the atomizer core is determined by a calculation method, such as Figure 2 As shown, this embodiment also provides a method for calculating the liquid guide hole 12, which includes the following steps:

[0042] Step 1: Obtain a first proportion based on at least one of the liquid absorption mass of the liquid-conducting medium 2 in a working state, the dynamic viscosity of the atomized liquid, and the cross-sectional thickness of the liquid-conducting medium 2, and the permeability of the liquid-conducting medium 2, the internal and external pressure difference of the liquid-conducting medium 2, the density of the atomized liquid, the area of ​​the adsorption surface of the liquid-conducting medium 2, and the working duration of the atomizing core each time.

[0043] For example, the first proportion is obtained according to the liquid absorption mass of the liquid-conducting medium 2 in the working state, the dynamic viscosity of the atomized liquid and the cross-sectional thickness of the liquid-conducting medium 2, the permeability of the liquid-conducting medium 2, the internal and external pressure difference of the liquid-conducting medium 2, the density of the atomized liquid, the area of ​​the adsorption surface of the liquid-conducting medium 2 and the working duration of the atomizing core each time.

[0044] Step 2: Obtain a second ratio according to the liquid absorption mass of the liquid-conducting medium 2 in a static state, and at least one of the area of ​​the adsorption surface of the liquid-conducting medium 2, the liquid conduction volume of the liquid-conducting hole 12, and a preset standard standing time.

[0045] For example, the second ratio is obtained according to the liquid absorption mass of the liquid-conducting medium 2 in a static state, the area of ​​the adsorption surface of the liquid-conducting medium 2, the liquid conduction volume of the liquid-conducting hole 12, and a preset standard standing time.

[0046] Step 3: Determine the proportion of the liquid-conducting hole 12 relative to the adsorption surface of the liquid-conducting medium 2 according to the first proportion and the second proportion; wherein the proportion is greater than or equal to the first proportion and less than or equal to the second proportion, and the first proportion is less than or equal to the second proportion.

[0047] It should be noted that step 1 and step 2 can be performed simultaneously, and the order of the two steps is not limited.

[0048] The present application constructs multiple related physical formulas for the atomizer core in the working state and in the static state, so as to associate the static state of the atomizer core with the working state, thereby associating the proportion (area size) of the liquid guide hole 12 with the static state and the working state, thereby obtaining a reasonable proportion of the liquid guide hole 12. The opening of the liquid guide hole 12 is reasonable and can be opened correspondingly for a specific atomizer core structure, not limited to a single atomizer core structure.

[0049] Specifically, the first proportion is obtained by the following formula 1: ε1=(M1×μ×L)÷(K×A×ΔP×ρ×b).

[0050] Wherein, μ is the dynamic viscosity of the atomized liquid (unit: Pa·s), M1 is the liquid absorption mass of the liquid-conducting medium 2 in the working state (unit: mg), K is the permeability of the liquid-conducting medium 2 (unit: mm 2 ), L is the cross-sectional thickness of the liquid-conducting medium 2 (unit: mm), ΔP is the pressure difference between the inside and outside of the liquid-conducting medium 2 (unit: Pa), and ρ is the density of the atomized liquid (unit: mg / mm 3 ), A is the area of ​​the adsorption surface of the liquid-conducting medium 2 (unit: mm 2 ), b is the working duration of the atomizer core each time (unit: s), and ε1 is the first proportion.

[0051] Specifically, the second proportion is obtained by the following formula 2: ε2 = M2 ÷ (A×v×a).

[0052] Wherein, M2 is the mass of liquid adsorbed by the liquid-conducting medium 2 in a static state (in mg), and A is the area of ​​the adsorption surface of the liquid-conducting medium 2 (in mm 2 ), v is the amount of liquid conducted by the liquid conducting hole 12 (unit: mg / (s·mm 2 )), a is the preset standard standing time (unit: s), and ε2 is the second proportion.

[0053] The proportion ε of the liquid-conducting hole 12 to the adsorption surface of the liquid-conducting medium 2 is ε1≤ε≤ε2.

[0054] The following is an example of the derivation process of Formula 1 and Formula 2.

[0055] The present invention establishes an equation for the equivalent relationship between physical quantities in static and working states, and obtains the following functional relationship:

[0056] (1) Static state

[0057] M2=A·v·ε·t2;

[0058]

[0059] Wherein, t2 is the static time of the atomizer core (unit: s), which needs to be greater than the preset standard static time a to ensure that the liquid-conducting medium 2 completely absorbs the atomized liquid and is completely soaked.

[0060] (2) Working status

[0061] During the working process, the flow rate of the liquid-conducting medium 2 is equal to the amount of atomized liquid replenished in the liquid storage tank 1. According to Darcy's law, the following equation is established:

[0062] M1=Q1·ρ·t1;

[0063]

[0064] Q1>Q2

[0065]

[0066] Wherein, t1 is the working time of the atomizer core (unit: s), which needs to be less than or equal to the working duration b of the atomizer core each time. The working duration b of the atomizer core each time can be understood as the maximum working time. Q1 is the total seepage flow rate of the atomized liquid penetrating into the liquid-conducting medium 2, and Q2 is the axial seepage flow rate of the atomized liquid penetrating into the liquid-conducting medium 2, both in mm 3 / s.

[0067] like Figure 3 As shown, although it is difficult to directly know the total seepage flow rate of the atomized liquid penetrating into the liquid-conducting medium 2, the seepage flow rate in the vertical direction, that is, the axial seepage flow rate, can be obtained. The total seepage flow rate is the sum of the liquid absorbed in the vertical direction and other directions, so multiple relationship equations about the above working state can be constructed, thereby obtaining the relationship between the working time and the proportion.

[0068] According to the above equation, we can get the following formula 1 and formula 2

[0069] Formula 1:

[0070]

[0071] That is, the first proportion can be obtained as: ε1 = (M1 × μ × L) ÷ (K × A × ΔP × ρ × b). This is because the maximum working time needs to be set for each atomization time of the atomizer core to avoid excessive load on the atomizer assembly 3. It can be seen that even if the actual working time of each time is unknown, it can be calculated by associating it with the maximum working time b to construct Formula 1 for the first proportion.

[0072] Formula 2:

[0073]

[0074] That is, the second proportion can be obtained as: ε2 = M2 ÷ (A × v × a). According to the relationship that the static time needs to be greater than the preset standard static time, the relationship between the second proportion and the standard static time a can be obtained.

[0075] The proportion ε of the liquid guide hole 12 can be obtained from the above formula 1 and formula 2, which can be expressed by the following formula 3:

[0076]

[0077] No matter in static or working state, except t1, t2 and ε, other parameters can be measured through experiments. Therefore, ε can be determined according to different times to calculate the size of the liquid guide hole.

[0078] In a practical application example, the liquid-conducting medium 2, the properties of the atomized liquid, and the parameters involved in the atomization process are as follows:

[0079] M2=20mg,v=0.00275mg / (s·mm 2 ), a=60s.

[0080] M1=8mg,ρ=1.261g / cm 3 , L = 2 mm, A = 162.286 mm 2 , μ=0.15Pa·s (50℃), ΔP=400Pa, K=1.732×10 -5 mm 2 , b=3s.

[0081] Among them, M1 and M2 can be measured by weighing method; K can be measured by a dedicated permeability test instrument; v can be obtained by atomized liquid tracer method and calculation; ΔP can be measured by a pressure test instrument; the remaining parameters are fixed values ​​and can be obtained directly.

[0082] Substituting the above parameters into Formula 3, we can obtain: 56.43%≤ε≤74.69%.

[0083] It can be determined that the percentage of the area of ​​the liquid-conducting opening to the surface area of ​​the adsorption surface should be between 56.43% and 74.69%, that is, the opening area should be controlled at 91.58 mm 2 ~121.21mm 2 Within the range.

[0084] The above examples are only for illustration and are not intended to limit the actual parameter values ​​of the parameters related to the atomizer core. By using the calculation method provided in this application, the liquid guide hole 12 of each atomizer core with a fixed structure can be calculated so that the size of the liquid guide hole 12 of the atomizer core is set within a reasonable range to ensure that there is no leakage when it is stationary and that the atomization effect is good when it is working.

[0085] Especially in the product design stage, the structure of the atomizer core can be designed on the computer software, and the working state can be simulated. At this time, various related parameters can be preset to obtain the proportion of the liquid guide hole 12. This speeds up the time cost required for the product design stage of the atomizer core.
